No, that's not how this works. Elon Musk existed before his Twitter purchase, he doesn't get a pass on literally everything he's done up until now.

You're moving the goalposts from the context of the thread.

There are no "goalposts" to move. Elon Musk has a well earned reputation, and it's impacting how I and others judge his actions related to Twitter.

This makes absolutely zero sense

...it makes no sense to consider someone's history when predicting their future performance?

If that doesn't make sense to you, not much will.
